Crankshaft Holding Clamp OS71530100 for RC Engine Servicing O.S. Engine  [OS71530100]

Crankshaft holding tool for RC repair

This RC crankshaft clamp is intended to keep the crankshaft stable while you carry out engine maintenance. It supports tasks such as checking bearings, replacing seals, and adjusting timing, and it does not claim compatibility with any single engine model. Consider it a universal-style clamp for matching crankshaft diameters.

For fitting: align the clamp to the crank snout, tighten symmetrically to avoid lateral loading, and ensure the shaft still turns freely before completing assembly. Use appropriate hand tools and conservative torque values to avoid damaging adjoining components. During setup and tuning it gives a repeatable shaft position for accurate adjustments.

When selecting a replacement, confirm the crankshaft diameter and nearby clearances on your engine. Consult manufacturer documentation when precise tolerances are required. The clamp is intended as a workshop aid and not as an engine modification.
